"WILLIAM M. HOFFMAN, OF BUFFALO, NEW YORK.

PUTTING-OUT MACHINE.

SPECIFICATION forming part of Letters Patent No. 323,334, dated July 28, 1885.

Application filed December 18, 1884,

To aZZ whom, it may concern.-

Be it known that 1, WILLIAM M. HOFFMAN, acitizen of the United States,residingin Butfa-lo, in the county of Erie and State of New York, have invented certain new and useful Improvements in PuttingOut Machines, of which the following is a specification.

The object of this invention is to provide the means for finishing the skin or hide complete-that is, when one operation is not sufficient, the skin or hide may be drawn back and forward through the rubber rollers by reversing the machine until the putting-out cylinder-blades have accomplished what in some cases could not be done in one operation. For instanco,when the hide is very heavy and the grain badly drawn up, a single passage through the rollers would not be sufficient to fully complete the puttingout or the ileshing process.

My invention is adapted to readily repeat the process as often as may be desired without taking the skin or hide from the machine until completed, all of which will be fully and clearly hereinafter shown by reference to the accompanying drawings, in which Figure l is a side elevation of the machine complete. Fig. 2 represents a detached side elevation showing the construction and arrangement of the gearing and mechanism for reversing the action of the machine, and Fig. 3 is a front view of the machine complete.

The frame a of the machine is made usually of cast-iron; but any other suitable material may be used.

a. a represent the putting-out cylinders. Z

They are mounted in bearings a in two double arms, a a, arranged so as to nearly balance and oscillate easily on the main shaft a. To the shaft o is aspuravheel, Z), rigidly secured. by a key or other well-known means. This wheel gears into a pinion, b, on the putting out cylinder a, and into a pinion, D which is mounted in bearings L on the arm a, so as to gear into the gear-wheel b on the puttingout cylinder a".

0 represents a large spur-wheel on the shaft 0, which gears into a pinion, c, rigidly fastened to the main shaft c 0 represent the rubber-covered rollers fer feeding the skin in or out of the machine. 011 the shaft of each of the rollers c c is a gear- (No model.)

wheel, 0 0 (shown in dotted lines in Fig. 1,) which gear together, so that when one roller moves the other moves also, as will be readily understood. To the shaft 0 is loosely fitted a rocking arm, (7, having the pinions d d al The shalt c is also provided with a spur-wheel, d rigidly secured thereto, and to the arm (I is jointed by a joint, g, a connecting-rod, d", which passes down and is jointed by joint 6 to the footstep frame 6; butthis rod may in some cases be dispensed with. The arms a are also connected by a joint, 0 to a rod, 6 which is jointed by a joint, 6, to the foot-step frame. The arm (Z is also provided with a hand-lever or arm, 0 to be used when the rod (2 is not used.

The rubbercovered feeding-rollers are provided with adjustable screws f, for regulating the pressure, and are mounted in boxes f f In Fig. 2, f represents the rubber covering on the rollers c c.

If desired, a counterweight, 1, may he placed on or secured to the foot-step, so as to produce an even balance of the parts.

The operation of the invention is as follows: The skin or hide being started in between the putting-out roller and the rollers 0 c in the direction of the arrows g, (the foot-step being pressed down on that side, as shown,) the skin is allowed to pass through as far as may be required. The foot-step is then pressed down from the opposite side, which reverses the action or the machine, and carries the skin back again until the other side of the foot-step is pressed down. During this operation the gearing moves as follow: The putting-out cylinders always work in the direction of the arrows 9 (See Fig. 2.) The wheel I), moving in the direction of the arrow g causes the cylinder a to move in the direction of the arrows while the connecting-pinion b causes the cylinder a? to move in the direction of its arrow 1 While the skin is advancing through the machine, the rubbercovered rollers c 0 move in the direction of the arrows ii, (see Fig. 2,) and during this movement the gearwhcel d turns in the direction of the rrows i causing the roller 0 to move, as shown by the arrow t. When the foot-step is reversed, the putting-out cylinders are in the position 1 shown by the dotted lines i i and the gear- 1 wheels d. d" are in the position. shown by the dotted lines j j In this position the Wheel d is out of action, while the gear-wheel d moves in the-direction of the arrow j as it receives its motion from the gear d and intermediate gear, 01 which moves in the direction of the arrow j It will now be seen that when the gear d is thus brought into -.gear with the gear on the roller 0 its motion will be reversed, and, if desired, the skin may at any time be held stationary between the rollers o c by holding the foot-step in such a position that neither of the wheels d or 01 will come into gear with the wheel d 1 claim as my invention-- 1. In a putting-out machine, two puttingout cylinders mounted in bearin gs upon oscillating arms in combination with a double connecting-rod, c jointed thereto and to a footstep, whereby either one of the putting-out cylinders may be brought into action against the roller 0 substantially as described.

2. The putting-out cylinder mounted in bearings on the arms a a, and the rubbercovered feeding-rollers and gearing, in combination with the oscillating arm d, provided with the gearing d d d, the gearing d, connecting-rods d e, and a foot-step, substantially as specified.

3. The combination of the rubber-covered feeding-rollers and connecting-gearing, the oscillating arm (I, mounted on the shaft 0, pinions d d d gear-wheel d and rod (1 for connecting the arm with the foot-step, whereby the action of the rollers may be reversed or stopped, substantially as described.

4. In a putting-out machine, the combination of two putting-out cylinders with the rubher-covered feeding-rollers, their voperatinggearing, and reversing mechanism, substantially as described, whereby the skin may be passed back and forth until complete, substantially as described.
